Application filed December 10, 1919. Serial No. 343,883.

To all whom it may concern Be it known that I, REGINALD W. BIRD, a citizen of the United States, residin at Framinfgham, in the county of Midd esex e and State of Massachusetts, have invented "new and useful Improvements in Shingle Strips, of which the following is a specification.

This invention has for its object to provide a novel shingle strip, which, when laid with others in overlapping relation, produces the effect of spaced individual shingles.

In accordance with the present invention a sheet of felt, saturated or impregnated with an asphaltic or bituminous compound of relatively low melting point, is coated with a molten or plastic layer of highermelting-point pitch or asphalt, and on the coating, while it is soft and lastic, is spread a surface layer of crushed fla iiy slate or other mineral of the desired color, say red, green or brown. This layer is partially embedded by pressure in the asphaltic coating, so that the entire surface of the sheet is thus provided with the mineral.

For the formation of the shingle strips to give them when laid the appearance of spaced individual shingles, the sheet is sub jected to the pressure of a roll which is provided with narrow ribs which act to embed the mineral materialengaged thereby completely into the plastic coa'tm'g so that the black coating appears and masks the mineral material. The sheet is then cut along lines approximately perpendicular to the black lines or stripes so formed, such lines of severance being spaced apart a dis-. tance equal to the desired width of the strip. The operating roll may have circumferential 4 ribs, in which event the sheet is cut crosswise into strips, or else the ribs may extend longitudinally of its axis in which event the sheet is cut lengthwise, and is, at intervals, chopped ofi to give to the strips the desired len h. I

' Figure 6 illustrates one of the strips.

Figure 7 represents in lengthwise section a portion of one of the shingle strips.

Figure 8 represents a portion of a roof coverlng comprising the stripsla-id 1n overlaplping relation.

he sheet of felt 10 is drawn through a vat 11 containing the bituminous waterproofing compound, and, after passingbetween the cooling rolls 12, 12, is coated with asphalt or pitch at 13, in passing between the rolls 14, 14. The crushed flaky slate is suppl ed tothe plastic coating by the hopper i5, and, in passin between the rolls 16, 16, the slate is partia y embedded therein, so that it entirely covers and conceals the bituminous coatin .The operations, as thus far describe are those commonly followed in making slate-surfaced roofing. After leaving the rolls 16, 16, with the coatingstillcomparatively softand plastic, the sheet is passed beneath a roll 17 which is provided with pressure ribs, equal in width to the spaces which are ordinarily left between individual shingles when laid on the roof, to wit, about half an inch. The roll, which is preferably heated, may have circumferential ribs 19 as in Figure 3. These ribs are of such depth as to force the particles of slate engaged thereby into and completely embed them in the bituminous coating, so that they are covered and masked thereby, and, being heated, soften the asphalt to assist in such embedment. The distance between the ribs is equal to the width of an ordinary shingle, e. g., five to six inches. If the black lines or stripes of depression are longitudinal of the sheet, the sheet is cut transversely on the line w-w, Figure 4, so that each strip severed therefrom is equal in length to the width of the sheet, and in width is about 12 inches, or to the length of an individual shingle. If the stripes of depression are transverse to the sheet as in Figure 5,'the sheet is out along the longitudinal lines 6-?) and is cut crosswise on'the line cc', thus producing shingle strips similar to those roduced from the sheet shown in Figure 4. e cuttin' machine is conventionally shown 7 at 20 in l igure 1, and the sheet'is sho as being festooned for cool In the conventional illustration of the strip no in Figure 7, the saturated body of the strip is indicated at e, arid the bituminous coating at f. The partially embedded slate is shown at g, while that which is wholly embedded is indicated at 71. Thus each strip, as shown in Figure 6. has the dark stripes or depressions 'Z and the slate-surfaced bands j, which are approxin'iately perpendicular to the top and bottom edges of the strip. When these strips are placed in overlapping relation on a roof. as represented in Figure 8, the roof presents the appearance of one having individual spaced shingles thereon.

lVhat I claim is:

1. A method of making shin'gle strips, adapted to be laid in overlapping relation in simulation of spaced individual shingles, consisting in partially embedding in the entire face of an asphalt-coated waterproofed fibrous sheet a surface layer of colored crushed slate, then by pressure completely embedding portions of the slate in parallel spaced stripes into said asphaltic coatingin contrast to the remainder of the slate-surfaced sheet, and then cutting said sheet transversely of said stripes into strips each having a plurality of such stripes perpendicular to its greatest diameter.

emma 2. A method of making shingle strips, adapted ,to be laid in overlapping relation in simulation of spaced individual shingles,

consisting in partiall embedding in theentire face of an aspha t-coated waterproofed fibrous sheet a surface layer of colored 3. A shingle strip, adapted. to be laid with others in overlappln relation in simulation of spaced individua shingles, consisting of a Waterproofed fibrous body having an asphaltic coating, bands of colored crushed slate partially embedded in such coating to conceal the same, and intervening stripes in which the slate is completely embedded so as to be masked by the asphaltic coating, said bands and contrasting intervening stripes being substantially perpendicular to the long top and bottom edges of the strip.

Intestimony whereof I have aflixed my signature".
